Answer first
A UK trade buyer should treat a vape hardware bill of materials (BOM) as a traceability and design-control document, not a supplier’s parts list. It should identify each assembly, material, revision and responsible party, then connect those details to the notified product format, reuse tests, packaging, waste duties and supply-chain records.
Key Takeaways - A useful BOM identifies the exact sellable configuration, not simply a device platform or marketing name. - Map liquid-containing parts, power components, refills and coils separately, because their regulatory and operational relevance differs. - Put version control, batch traceability and packaging artwork under the same change-control process as hardware. - Request evidence before purchase, and record who is responsible for notification, waste obligations and product traceability.
Start with the exact configuration that will be supplied
A purchase decision should begin with a configuration-level BOM: unique SKU, brand, hardware and packaging revisions, plus a drawing or exploded view. List every supplied element, including body, battery, charging interface, heating assembly, tank or pod, seals, instructions and outer pack. A platform-level list cannot establish the configuration actually supplied.
For Great Britain, manufacturers and importers must notify electronic cigarettes and refill containers intended for the market. MHRA treats device-only, refillable, rechargeable, kits and liquid-containing parts as distinct formats. Tanks, atomisers and cartridges are relevant; generic batteries and mouthpieces are not treated the same way. See MHRA e-cigarette product types in Great Britain.
Ask: which BOM revision, brand and product format map to the GB notification record? A notification listing is not product approval. Match it to the physical configuration and accountable business. Confirm the route separately where stock is also intended for Northern Ireland.
Test reusability through the component structure
A rechargeable battery alone does not make a vape reusable. Since 1 June 2025, businesses cannot sell, supply, offer or hold for supply a single-use vape. Defra says a reusable vape needs a rechargeable battery, refillable liquid container and, if it has a coil, a user-removable and replaceable coil. Refills and relevant coils should be separately available (Defra guidance).
Give the device, refill pod or tank, compatible refill, coil or coil-containing pod and charging solution distinct part numbers. Ask how each is replaced and retain evidence of separate availability. Ask: which parts prove reusability for this configuration? A UK reusable-vape explainer can align terminology.
| BOM area | Question for the supplier or responsible party | Record to retain |
|---|---|---|
| Product identity | What are the model, SKU, brand and hardware/packaging revisions? | Controlled BOM and artwork version |
| Liquid-containing part | Is it a tank, pod, cartridge or fixed combination, and what is its capacity? | Drawing, part number and GB notification mapping |
| Battery and charging | Is the battery rechargeable, and which charging components are supplied or specified? | Electrical specification and instructions |
| Refill and coil route | How are the refill and, where present, coil replaced, and are they separately available? | Compatibility list and availability evidence |
| Traceability | Which batch or serial reference links hardware, packaging and delivery? | Batch record, invoice and delivery note |
Put notification, packaging and traceability under change control
A BOM needs a change-control owner. MHRA says a new notification is required for a substantial modification, including a tank or cartridge volume change or device design or power-output change likely to affect emissions; its guidance gives six months’ advance notice. Before accepting a substitute, identify the BOM revision and confirm notification status has been reviewed (MHRA submission-type guidance).
Treat packaging as a BOM component. For nicotine-containing electronic cigarettes and refill containers, MHRA guidance addresses presentation of the unit packet and outside packaging, including restrictions on misleading health, comparative-safety, lifestyle and environmental claims. Verify the supplied artwork, leaflet, warnings, brand and identifiers against the controlled file. See UK vape packaging and labelling.
OPSS advises including manufacturer and, where applicable, importer contact details, plus a product or batch reference identifying manufacture (OPSS guidance). Include these fields in goods receipt.
Check the supply-chain records that sit around the hardware
Name the UK entity responsible for each obligation. Vaping Products Duty applies to vaping liquid whether or not it contains nicotine, including liquid in pods and cartridges. Since 1 October 2026, liable products released onto the UK market require a duty stamp. HMRC asks wholesalers and retailers to check required stamps, their placement, origin and commercial records, and to retain records for at least six years (HMRC guidance).
Map the liquid-containing part to the retail pack. Keep invoices, delivery notes, supplier identity, batch/SKU detail and any explanation for unstamped stock. From 1 April 2027, HMRC says unstamped products outside duty suspension must not be sold or held; do not assume a historic stock position applies to new purchases.
Vapes are electrical items covered by WEEE rules, and vape distributors must offer takeback for returned vapes and parts. A commercial importer or own-brand seller can be an EEE producer with registration, reporting, marking and record-keeping duties (EEE producer guidance). Establish the responsible UK entity and takeback route before stock moves. See UK vape recycling and WEEE takeback.

Frequently Asked Questions
What should a vape hardware BOM contain?
It should identify supplied components, part numbers and revisions, retail configuration, compatible refills and replacement parts, packaging and instruction revisions, and batch or serial traceability. Assign a document owner and change-approval route.
Do replacement parts need the same notification treatment as a device?
Not necessarily. Under MHRA’s GB product-type guidance, an essential part capable of containing nicotine liquid, such as a tank, atomiser or cartridge, is within scope. Generic replacement batteries or mouthpieces are not treated the same way. Match the part’s function and supplied format to the guidance.
What should a buyer do when a supplier proposes a hardware substitution?
Pause the substitution until the supplier or responsible party identifies the affected BOM revision, notification mapping, packaging impact and traceability record. A change to a device’s design or power output that is likely to affect emissions may be a substantial modification under MHRA guidance. Record the decision before receiving altered stock.
